P-M去噪模型及仿真实现

The P-M image denoising model and simulation

基于P-M方程的图像去噪模型是一种非常有效的方法,且具有各向异性。给出了离散迭代格式,通过C++仿真实验验证了算法对抑制噪声的有效性,实验结果显示,该算法比线性方法更好地保持了边缘、纹理和细节,且峰值信噪比得到有效提高。

The P- M mage denoising model is an effective method which is anisotropic. This paper presents a method of discrete scheme. The experimental results demonstrate the effectiveness of this algorithm, also show that this method has advantages in preserving both the edge and the texture. The PSNR value is increased effectively
